With saunas becoming more crucial in wellness routines, the demand for technology that can withstand extreme heat and humidity is rising. Many want to track calories burned, heart rate, or recovery metrics during a sauna session.
However, not all wearables can withstand sauna heat and humidity. Let us explore what to look for, what to avoid, and how to get the most out of your technology without compromising your health or device.
What to Look for in a Sauna-Compatible Wearable
Are you looking for the best wearable for your outdoor infrared sauna session? Here is what to consider.
Temperature Resistance
The device you pick must withstand high temperatures and prolonged exposure to humidity. Look for wearables that are built to endure above-average temperatures. Ensure they are tested to industrial or military standards. This assures you that internal components and batteries will not degrade or malfunction when exposed to extreme heat.
Minimal Electronics Exposure
Opt for wearables with streamlined designs that have fewer external openings or sensors. Devices without screens or minimal external ports are less likely to suffer damage. Wearables like minimalist trackers or fitness rings are ideal because they minimize heat absorption and have no vulnerable display elements.
Water and Steam Sealing
Choose devices with advanced sealing technology to prevent steam penetration. High IP ratings, such as IP68 or higher, indicate strong protection against water and dust. Still, it is important to check if steam-specific resistance has been tested. Remember, steam can cause gradual internal damage that only surfaces weeks or months later.
Tips for Using Wearables in the Sauna
Your wearable device will fail if you do not follow best practices. These tips help protect your skin and extend the life of your device.
Use them in Infrared Saunas
The best infrared saunas operate at lower temperatures and emit heat penetrating the body without significantly heating the surrounding air. The lower ambient temperature makes it safer for electronics and reduces the risk of thermal damage to your wearable.
Tip: Users considering a personal setup should research the best infrared sauna for home to ensure compatibility with heat-sensitive wearables and optimal tracking conditions. For tips on sauna purchasing, read: How to Buy an Infrared Sauna in 2026
Cover the Wearable with a Towel
Wrapping a small sweatband or towel around your device helps block direct exposure to steam and heat. This simple barrier can reduce the rate of heat absorption and protect sensitive sensors or screens.
Limit Session Duration
Prolonged exposure to high temperatures is risky. Wear your device only for the first 5 to 10 minutes of your sauna session to capture initial physiological changes, then remove it for the remaining part of your session. Doing so strikes a balance between data collection and device preservation.
Let Your Devices Cool Naturally
After exiting the sauna, place your wearable in a shaded, cool area to gradually return to the surrounding temperature. Do not rinse it with cold water because it can cause internal components to contract suddenly, resulting in cracks or condensation damage.
What to Avoid When using Wearable Sauna Accessories
Using Wearables in Steam Rooms
The water vapor in steam rooms is more invasive than dry heat. Waterproof devices can allow steam to seep into internal components, causing long-term corrosion or electrical failure.
Wearing Metal Bands
Metal accessories can become dangerously hot, posing a burn risk. Stick with non-metal, heat-resistant materials that remain comfortable and safe against the skin during high-heat sauna sessions.
Fast Charging After Sauna Use
Your device might retain residual heat internally. Plugging it into a charger too soon can stress the battery, leading to swelling or permanent capacity loss. Allow your device to return to room temperature first before charging it.
How to Clean and Maintain Wearables After Sauna Use
Cleaning your device after the best outdoor sauna session is crucial for hygiene and longevity. Sweat, oils, and heat can accumulate and degrade materials over time, especially in humid environments. Here are post-sauna maintenance tips.
Wipe Down Immediately
Use a soft, dry microfiber towel to wipe away any sweat and moisture from the surface. Avoid rough clothes that can scratch the display or sensor areas. Use warm water and mild soap to gently clean any salt buildup from sweat without damaging the device.
Remove the Band
If your wearable device allows, detach the band and soak it in lukewarm water and mild soap. This helps remove accumulated sweat salts, grime, and bacteria. Rinse thoroughly and let it air dry completely before reattaching to avoid trapping moisture next to your skin.
Avoid Alcohol-Based Cleaners
While alcohol can kill germs, it can degrade waterproof coatings, adhesives, and soft-touch materials. Stick to gentle cleansers that will not corrode or dry out essential parts of your wearable gadget.
Store in a Cool Place
Never leave your wearable in a closed car, sealed gym bag, or locker immediately after sauna use. Trapped heat and moisture can accelerate wear and create the perfect environment for mold, mildew, or corrosion. Instead, store the device in a dry, shaded area where it can breathe and cool off naturally.
Sauna-Compatible Wearables to Consider
Are you looking to incorporate tech into your home sauna sessions? Here are sauna-compatible wearables to consider.
Fitness Rings
Fitness rings are a top choice for the best home sauna users because of their minimalist design and durable build. Here are their Features.
Low Surface Area: Fitness rings are small and made of heat-resistant materials like ceramic or titanium. They have a limited surface area, absorbing and retaining less heat, making them more comfortable to wear in high-temperature environments.
Passive Monitoring: These rings often track temperature fluctuations, heart rate, and sleep data passively without requiring user interaction. They have no screens or charging ports, making them less vulnerable to heat and steam damage.
Lightweight and Discreet: Fitness rings are ideal for users who prefer a minimal feel. Their low profile makes them comfortable even when sweating heavily or changing postures inside the home sauna.
Screen Less Fitness Bands
The features of screen less fitness bands include:
Minimal Electronics Exposure: Screen less fitness bands have no display or haptic feedback systems, reducing the risk of malfunction or screen warping under heat. They are often sealed tightly, preventing moisture from penetrating.
